The NASCAR X-Finity Series  also visits Auto Club Speedway this weekend for Saturday’s Treat My Clot-dot-com 300. Kevin Harvick is the defending winner and returns seeking back-to-back victories driving the Number-88 Junior Motorsports Chevrolet. If successful, he would become just the fourth driver to double up there since Auto Club Speedway first hosted the X-FINITY Series in 1997: joining Matt Kenseth, who went back-to-back in 1999 and 2000.

Greg Biffle, who swept both races in 2004 … and Kyle Busch in 2008 and 2009, and again in 2010 and 2011 … Toyota has won nine of the last eleven X-FINITY Series races contested on the two-mile Southern California oval with six of those wins courtesy of Busch – who also has three poles at A-C-S. Each time he’s started an X-FINITY Series race from the Number-1 spot, that’s also where he’s finished the race.
